Ball Mill failure reason
Ball Mill is a kind of milling equipment widely used in mines, cement plants and chemical plants. It is one of the important equipment for deep processing of non-metallic minerals. Due to the stable performance, adaptability and cost performance of the Ball Mill, it has been widely used in the processing of non-metallic minerals since its introduction in China for more than 20 years.
The Ball Mill encounters problems such as reduced powder output during use, and can be handled as follows:
Fault one: no powder or no powder, low yield
The cause of the failure: 1, the locker is not adjusted well, the seal is not strict, causing the powder to suck. 2, the blade wears a lot, the material can not afford to shovel. Remedy: 1. Check and adjust the seal of the locker and find that the air leak should be scraped. 2. Replace the new blade.
Fault 2: The finished powder is too thick or too fine
The cause of the failure: 1. The blade of the analyzer is seriously worn and cannot be graded. 2. The fan air volume is not appropriate. Remedy: 1. Replace the length of the blade and turn off the air volume of the small fan to solve the rough. 2, too fine should increase the volume of imported air.
Fault three: the vertical mill main current rises, the fan current drops
The cause of the failure: 1. The feed is excessive, the air passage is blocked by the powder, the exhaust of the pipeline is not smooth, the circulating airflow generates heat, the main current, the machine temperature rises, and the fan current decreases. Remedy: 1, reduce the amount of feed, remove the wind tunnel powder. 2. Open the large air duct valve, and the temperature of the incoming material is controlled below 6 °C.
Fault 4: Ball Mill main engine is noisy and has large vibration
The cause of the failure: 1, the amount of feed is small. The blade is severely worn, the material cannot be shoveled, and the anchor bolts are loose. 2, the material hard impact is large, or the material layer 3, the grinding roller grinding ring is seriously deformed. Remedy: 1. Adjust the feeding amount and replace the new blade. 2. Replace the feed size. 3. Replace the grinding roller and grinding ring.
Fault 5: Fan vibration
The cause of the failure: 1. The powder on the wind blade is uneven or worn. 2. The anchor bolts are loose. Remedy: 1. Remove the leaf powder or replace the blade. 2. Tighten the anchor bolts.
Fault 6: The transmission of the Ball Mill and the fuel tank of the analysis engine
The cause of the failure: 1. The viscosity of the oil is large and the oil is thick. The thread pump oil cannot be used to make the upper bearing lack of oil. Remedy: 1. Check if the oil grade and viscosity match the requirements. 2, check the direction of the analysis machine
